During aerobic exercise, your heart pumps oxygenated blood to working muscles to help them burn fat and carbohydrate for fuel, which in turn enables you to perform for extended periods.\u00a0<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">In contrast, anaerobic activity such as sprinting means \u2018without oxygen\u2019. Because anaerobic exercise such as sprinting is performed at a higher intensity your heart is unable to deliver oxygenated blood to your muscles, which is why you can\u2019t maintain your intensity for long periods.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">Training for aerobic endurance is more commonly referred to as <\/span><i><span data-contrast=\"none\">cardio<\/span><\/i><span data-contrast=\"none\"> because it uses the cardiorespiratory system (heart, lungs, veins, arteries, portal vessels and coronary vessels). As a result, aerobic endurance is known by many other names including <\/span><i><span data-contrast=\"none\">cardiovascular endurance<\/span><\/i><span data-contrast=\"none\">, <\/span><i><span data-contrast=\"none\">cardiorespiratory endurance<\/span><\/i><span data-contrast=\"none\">, <\/span><i><span data-contrast=\"none\">cardiovascular fitness<\/span><\/i><span data-contrast=\"none\">, and <\/span><i><span data-contrast=\"none\">cardiorespiratory fitness<\/span><\/i><span data-contrast=\"none\">. It\u2019s also referred to as <\/span><i><span data-contrast=\"none\">aerobic fitness<\/span><\/i><span data-contrast=\"none\"> or its most basic term, <\/span><i><span data-contrast=\"none\">stamina<\/span><\/i><span data-contrast=\"none\">, but their definitions are identical: your ability to keep exercising at moderate intensity for extended periods of time.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h3><b><span data-contrast=\"none\">Why improve your aerobic endurance?<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/h3>\n<p><span data-contrast=\"none\">Even if you don\u2019t play or compete in sport, improving your aerobic fitness through physical activity will lower your heart rate and go a long way to reducing your risk of heart disease and other health conditions. Whatever the type of exercise, it will hugely benefit your entire cardiorespiratory system.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">As an athlete, professional or otherwise, endurance exercise will also improve your VO2 max. Your VO2 max is a measurement of the maximum amount of oxygen you can utilise during intense or maximal exercise. The better your VO2 max, the more efficient your body becomes at consuming oxygen from blood, so you can work out at a higher intensity for extended periods and go for longer distances.<\/span><span

data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/h3>\n<p><span data-contrast=\"none\">A staple form of endurance training for most people is running, cycling and swimming. But it\u2019s a misconception that the only way to gain aerobic endurance is to stick to these activities and these activities alone, especially if you\u2019re an athlete. The truth is, there are many ways to train for aerobic endurance, including strength training, which make use of different energy systems, so well-balanced training programs consisting of a variety of adaptations will yield the best results and give you a more well-rounded level of cardiovascular fitness.\u00a0<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">If you\u2019re training for an endurance event, your focus should be on improving your c<\/span><span data-contrast=\"none\">ardiorespiratory endurance. But even then it should be combined with a number of other training methods. For example, while the nature of sprinting is anaerobic, a sprinter benefits hugely by including longer aerobic distances.<\/span><span data-contrast=\"none\"> Consider the duration and intensity of your training as well as the frequency to maximise the benefits. While frequency is open to debate, you won\u2019t go far wrong if you aim to complete three to five 30-minute sessions <\/span><span data-contrast=\"none\">per week<\/span><span data-contrast=\"none\">.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h3><b><span data-contrast=\"auto\">Types of training to improve your aerobic endurance<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/h3>\n<p><span data-contrast=\"none\">There are a number of more modern and popular training methods including Concurrent Training and CrossFit that increase strength and endurance simultaneously. But there are many tried and tested training types used by amateur and professional athletes that have stood the test of time and are guaranteed to improve your aerobic endurance.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h4><span style=\"color: #ffcc00\">Long and slow\u00a0<\/span><\/h4>\n<p><span data-contrast=\"none\">Long and slow-paced runs, cycles and swims are the most common types of endurance training that require moderate intensity and rely on sustained energy outputs. This type of training is routinely undertaken by elite athletes as part of their wider training programs, and it is also ideally suited to novices and older exercisers owing to the lower intensity that puts less stress on the body.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h4><span style=\"color: #ffcc00\">Pace or tempo training\u00a0<\/span><\/h4>\n<p><span data-contrast=\"none\">Training at a set tempo essentially refers to the speed at which your perform your reps. Whatever your physical activity, it has multiple benefits for aerobic and muscular endurance that will make you stronger and able to perform for longer and harder. For runners it means a pace that could be defined as comfortably hard. Tempo runs are designed to challenge how fast you can still run aerobically and are done at lactate threshold (a metabolic by-product of exercise and the point at which lactate begins to accumulate in the blood at a faster rate than it can be removed). Recognising if you\u2019re training beyond your lactate threshold is easy as you\u2019ll feel a familiar burning sensation in your muscles and you\u2019ll fatigue quickly.\u00a0<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h4><span style=\"color: #ffcc00\">Interval training\u00a0<\/span><\/h4>\n<p><span data-contrast=\"none\">Interval training is typically used for physical activities such as running, cycling, swimming, rowing, and weight training and consists of a number of periods of high intensity interspersed with \u2018rest\u2019 periods involving physical activity of lower intensity. Interval training is incredibly effective for improving both aerobic and anaerobic energy systems because the level of intensity during periods of exertion are close to anaerobic exercise. For athletes, it\u2019s also very effective for increasing your VO2 max<\/span><span data-contrast=\"auto\"> and anaerobic threshold, which ultimately translates to being able to work harder and maintain intensity for longer.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h4><span style=\"color: #ffcc00\">Circuit training\u00a0<\/span><\/h4>\n<p><span data-contrast=\"auto\">An old favourite and one of the best customisable training methods, circuit training consists of a number of exercises with equipment or bodyweight performed in a circuit for short durations and rotated through with little or no rest between stations. Circuit training typically includes both strength and endurance exercises and is one of the most effective all-round fitness training models that can easily be made sport-specific to help you reach your training goals.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h4><span style=\"color: #ffcc00\">Fartlek training\u00a0<\/span><\/h4>\n<p><span data-contrast=\"auto\">Translated literally, Fartlek means \u2018playing around with speeds\u2019, which makes for an unstructured but fun training session. Fartlek training effectively involves a continuous run for typically between 45-60 minutes during which you vary the intensity and speed of your run (it can even include walking) to improve your endurance, strength and overall fitness. Other benefits of Fartlek training include practicing mind over matter, which improves your ability to find another gear during competition.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<h4><span style=\"color: #ffcc00\">Weight or resistance training\u00a0<\/span><\/h4>\n<p><span data-contrast=\"auto\">Weight training provides stress to your muscles that forces them to adapt and get stronger in a similar way that aerobic conditioning strengthens your heart. Resistance training programs complement all forms of endurance training exceptionally well and they\u2019re an important training type of professional athletes whose events are solely endurance-based. Your muscles get stronger to better cope when they\u2019re put under the stress of endurance activity, and blood vessels (arteries) in your working muscles vasodilate (get bigger) to allow more blood flow to those muscles. Usually involving as little as one or two sessions per week interspersed with your normal endurance work, exercises should be performed at low intensity at around 60% of your one rep max with high repetitions and short rest periods.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Even if you don\u2019t play or compete in sport, improving your aerobic fitness through physical activity will lower your heart rate and go a long way to reducing your risk of heart disease and other health conditions.
